This type of small agricultural machinery isn't really the main machinery being promoted by Yang Zhengxi's family.
The purpose of developing them, well, is purely because this market is vacant, so why not let them occupy it first.
As for sales, there's no expectation.
After all, it's well-known that the real big grain producers who are willing to spend money on machinery are all concentrated in the plains and vast areas.
These farm machines aren't very large, talking about the area they cover, they might be even smaller than the little cars kids like to drive around now. Young women and the elderly can operate them for tasks like digging, loosening soil, and harvesting.
The advantage is that they are suitable for various terrains, especially mountainous and hilly areas, including some very narrow terraced fields.
The disadvantage is that they can't completely free up labor, and their efficiency is relatively low compared to big agricultural machines.
